听力原文：M: May I see Dean Williams please? W: Dean Williams won't be in the office this afternoon. I'm an assistant dean, perhaps I can help you. M: I need an extension for a paper, and my professor said I had to get special permission from the dean's office. W: For what course? M: Economics 201, Professor Brown's course. W: Is this a term paper or a paper written instead of a final exam? M: It's to take the place of final exam. W: So, ordinarily, it would be due on the last day of exam period, which is this Friday, that's two days away. Don't you think you could have the paper finished by then? M: I haven't even started it yet. You see, I've been sick since last Saturday with tonsillitis (扁桃腺炎). I just checked out the clinic this morning. W: So you were in the clinic for four days. M: Yes, from Saturday until today, Wednesday. W: Generally, for an illness like this, we can postpone the exam, or the due day of a paper that takes the place of an exam by the number of days the students have been ill, in your case, by four days. M: That means I'll be able to hand in my paper next Tuesday instead of this Friday? W: That's right, but first you have to fill out this form, giving the name of the course, your reasons for needing the extension and so on, then take the request to the clinic to have it signed by the doctor then bring it back to me today, and I'll have a copy sent to Professor Brown. M: Thank you very much. I'll see you late this afternoon with the completed form. W: I'm glad you are feeling better. (29)
